From the table, we calculated the square of hail speed by 0.047~0.049 equals hail diameter. Thus we
calculate the hail air resistance coefficient. When the hail free fallers accelerated to a certain stag, hail
gravity and hail resistance balance final constant speed landing. Based on the above principles, our hail
tester is for hail and shells by the pneumatic acceleration. When cartridge from gun, hail with constant
speed bumps after components.
Vertical firing mode, solved technical problems of the acceleration of gravity of hail and speed deviation.
In order to avoid the hail breached, we give the hail added a protective device hail shell, or cartridge. The
diameter of hail shell and the gun shell is very consistent. The diameter of it and the shell, very consistent

IEC 62716 "Ammonia corrosion testing of photovoltaic (PV) modules":2010 (draft-B/C)
Photovoltaic modules commonly used aluminum alloy frame, UL 1703 test subject is galvanized material
(a module constructed of materials such as plastic, stainless steel, or aluminum that are inherently resistant
to atmospheric corrosion need not be tested), corrosive atmosphere test already can not adapt to the need
of photovoltaic industry. The following key Introduction Ammonia corrosion testing.
Ammonia corrosion test conditions:
Cycles
1 test section
Hours 8 including heating up
NH3 - Concentration 6,667 ppm
Temperature 40 ± 3°C (maybe draft-C require 60°C)
rel. Humidity Saturation at about 100% (dewing of the samples)
2 test section
Hours 16 including cooling (Test chamber opened and/or
ventilates)
NH3 - Concentration 0 ppm
Temperature 18 to 28°C
rel. Humidity Maximum 75% (maybe draft-C require 100%)
The concentration is related to the volume of the test chamber and corresponds to a ground quantity of
water of 2 litres with a chamber volume of 300 litres.
During testing the inclination to the vertical of the face of the PV module normally exposed to solar
irradiance shall be 15° to 30° inside the climatic chambers.
Test reference ISO 12944, ISO 3231, ISO 6988 and DIN 50018 relevant provisions.
Molecular filter: Ammonia external emissions should not exceed 5% of the total test Concentration, we
must purify exhaust emissions.
Ammonia measurement: PID for high concentration measurement, range 0~10,000ppm
Safety detector: LEL sensor, range 0~100% LEL (The lower explosive limit of Ammonia: 15%)
Mothed: Dominant potential failure mechanisms in the reaction of ammonia with PV modules are
identified by applying different ammonia concentrations to PV modules and its components (encapsulation
materials, front glass...) and evaluating the damage mechanisms by various analytical methods. The
permeation of ammonia through encapsulant and back skin materials (EVA and Tedlar/ PET/ Tedlar) are
evaluated quantitatively.

BR-PV-SED Sharpness of Edge Determination Equipment
Perform standards: IEC 61730-1:2004, UL 1703-2012, UL 1439-2004
Edges, projections, and corners of photovoltaic modules and panels shall be such as to reduce the risk of
injury to persons.
Whenever a referee measurement is necessary to determine that a part as mentioned in 6.9 is not sufficiently
sharp to constitute a risk of injury to persons, the method described in the requirements in the standard for
Determination of Sharpness of Edges on Equipment, UL 1439, is to be employed.
The test apparatus is to consist of the following: a) Sharp-Edge Tester – The instrument consists
essentially of a handle with a pivoted arm attached. A
constant-tension spring secured to the handle is used to
apply a steady force to the arm. The arm head is a piece
of round steel, with an outside diameter of 12.7mm
located at the end of the adjustable arm. The arm head is
to be wrapped with three layers of tape, the two outer layers act as sensing tapes; the inner
layer acts as an indicating tape, or the tapes are to be applied to a 15.9mm removable sleeve
that is placed onto the 12.7mm steel head.
b) Indicating Tape (Inner Layer) – 19.1mm wide, adhesive backed, single-adhesive coated,
vinyl foam tape, black in color, having the tape properties given in Table 5.1.
c) Sensing Tape No. 2 (Middle Layer) – 19.1mm wide, double-adhesive coated, vinyl foam
tape, white in color, having the tape properties given in Table 5.1.
d) Sensing Tape No. 1 (Outer Layer) – 19.1mm wide, single-adhesive coated skived tetrafluorethylene
tape – natural color, having the tape properties given in Table 5.1. The skived tetrafluorethylene backing
(film) is shaved in a thin layer from a cylindrical block of material.
e) Calibration Equipment – A weight that can exert 6.7N and a length of string.
Test Procedure: The curved face of the tester head shall be covered with three layers of tape in the order indicated below:
a) First Layer (Inner Layer) – Indicating type, black vinyl foam tape as described in 5.1(b).
b) Second Layer (Middle Layer) – Sensing Tape No.2, white vinyl foam tape as described in 5.1(c).
c) Third Layer (Outer Layer) – Sensing Tape No.1, tetrafluorethylene tape as described in 5.1(d). Each
tape is to be applied over approximately 180 degrees of the circumference of the test head to prevent
stretching of the tape.
The tapes are not to be stretched when positioned on the head.
The center of the tape-covered head of the sharp-edge tester shall be positioned on the edge to be tested in
the manner illustrated in Figure 7.2. The arm of the tester shall be between stops so that the tape-covered
head exerts a 6.7N on the edge. The tester shall be immediately moved along the edge a distance of 50.8mm
and then back to its starting position without removal of the tester from the edge. It shall then be withdrawn
from the edge. The total distance of engagement between the edge and the tape-covered head is not to
exceed 101mm. The time of travel is not to take longer than 5 seconds nor less than 2 seconds.
Exception: An edge less than 50.8mm long shall be tested for a distance of twice its length.
(Example: For an edge 41.2mm long, the tester is to be moved along its length and back to the starting
position so that the total distance of engagement between the edge and tester is 76.2 mm.

BR-UL-MCT Metallic Coating Thickness Test System
Perform standards: UL 1703-2012, ASTM B499-2009, ISO 2178-1995
The test for corrosive atmosphere Test, include salt spray test and moist carbon
dioxide / sulphur dioxide, measure the thicknees of coating on Zinc-coated
(galvanized) Iron or steel articles. Recommend ASTM B499 and ISO 2178
Nonmagnetic coatings on magnetic basis metals measurement of coating method.
UL 1703-2012 use mass loss method (chemical method), Maneuverability is not
strong, and chemical reagent may pollute the environment.
The method for determining the thickness of a zinc or cadmium coating mentioned
in 14.1 and 14.2 is described in following.
The solution to be used for the metallic coating thickness test is to be made from distilled water and is to
contain 200g/L of reagent (or better) grade chromium trioxide (CrO3) and 50g/l of reagent (or better) grade
concentrated sulfuric acid (H2SO4). The latter is equivalent to 27ml/l of reagent grade concentrated
sulphuric acid, specific gravity 1.84, containing 96 percent of H2SO4.
The test solution is to be contained in a glass vessel such as a separatory funnel with the outlet equipped
with a stopcock and a capillary tube of approximately 0.64 mm inside bore and 150mm long. The lower
end of the capillary tube is to be tapered to form a tip, the drops from which are about 0.05 milliliter each.
To preserve an effectively constant level, a small glass tube is to be inserted in the top of the funnel through
a rubber stopper and its position is to be adjusted so that when the stopcock is open, the rate of dropping
is 100±5 drops/min. If desired, an additional stopcock may be used in place of the glass tube to control the
rate of dropping.
The sample and the test solution are to be kept in the test room long enough to acquire the temperature of
the room, which should be noted and recorded. The test is to be conducted at a room temperature of
21.2°C~32.0°C.
The sample is to be thoroughly cleaned before testing. All grease, lacquer, paint, or other nonmetallic
coatings, including skin oils, are to be removed completely by means of solvents. The sample is then to be
thoroughly rinsed in water and dried with clean cheesecloth.
The sample to be tested is to be supported from 17mm to 25mm below the orifice. The surface to be tested
shall be inclined at approximately 45 degrees from the horizontal so that the drops of solution strike the
point to be tested and run off quickly.
The stopcock is to be opened and the time in seconds is to be measured until the dropping solution dissolves
the protective metal coating, exposing the base metal. The end point is the first appearance of the base
metal recognizable by the change in color at that point.
The sample of a test lot is to be subjected to the test at three or more points, excluding cut, stenciled, and
threaded surfaces, on the inside surface and at an equal number of points on the outside surface, at places
where the metal coating may be expected to be the thinnest. (On enclosures made from precoated sheets,
the external corners that are subjected to the greatest deformation are likely to have thin coatings.)
To calculate the thickness of the coating being tested, select from following the thickness factor appropriate
for the temperature at which the test was conducted and multiply by the time in seconds required to expose
base metal as noted in 38.7.
